BACKGROUND OF THE INVENTION

2. Description of the Related Art

Corticotropin releasing factor (herein referred to as CRF), a 41 amino acid peptide, is the primary physiological regulator of proopiomelanocortin (POMC)-derived peptide secretion from the anterior pituitary gland (J. Rivier et al., Proc. Nat. Acad. Sci. (USA) 80:4851 (1983); W. Vale et al., Science 213:1394 (1981)). In addition to its endocrine role at the pituitary gland, immunohistochemical localization of CRF has demonstrated that the hormone has a broad extrahypothalamic distribution in the central nervous system and produces a wide spectrum of autonomic, electrophysiological and behavioral effects consistent with a neurotransmitter or neuromodulator role in brain (W. Vale et al., Rec. Prog. Horm. Res. 39:245 (1983); G. F. Koob, Persp. Behav. Med. 2:39 (1985); E. B. De Souza et al., J. Neurosci. 5:3189 (1985)). There is also evidence demonstrating that CRF may also play a significant role in integrating the response of the immune system to physiological, psychological, and immunological stressors (J. E. Blalock, Physiological Reviews 69:1 (1989); J. E. Morley, Life Sci. 41:527 (1987)).

Clinical data have demonstrated that CRF may have implications in psychiatric disorders and neurological diseases including depression, anxiety-related disorders and eating disorders. A role for CRF has also been postulated in the etiology and pathophysiology of Alzheimer's disease, Parkinson's disease, Huntington's disease, progressive supranuclear palsy and amyotrophic lateral schlerosis as they relate to the dysfunction of CRF neurons in the central nervous system (for review see E. G. De Souza, Hosp. Practice 23:59 (1988)).

In affective disorder, or major depression, the concentration of CRF is significantly increased in the cerebral spinal fluid (CSF) of drug-free individuals (C. B. Nemeroff et al., Science 226:1342 (1984); C. M. Banki et al., Am. J. Psychiatry 144:873 (1987); R. D. France et al., Biol. Psychiatry 28:86 (1988); M. Arato et al., Biol. Psychiatry 25:355 (1989)). Furthermore, the density of CRF receptors is significantly decreased in the frontal cortex of suicide victims, consistent with a hypersecretion of CRF (C. B. Nemeroff et al., Arch. Gen. Psychiatry 45:577 (1988)). In addition, there is a blunted adrenocorticotropin (ACTH) response to CRF (i.v. administered) observed in depressed patients (P. W. Gold et al., Am J. Psychiatry 141:619 (1984); F. Holsboer et al., Psychoneuroendocrinolgy 9:147 (1984); P. W. Gold et al., New Eng. J. Med. 314:1129 (1986)). Preclinical studies in rats and non-human primates provide additional support for the hypothesis that hypersecretion of CRF may be involved in the symptoms seen in human depression (R. M. Sapolsky, Arch. Gen. Psychiatry 46:1047 (1989)). There is preliminary evidence that tricyclic antidepressants can alter CRF levels and thus modulate the number of CRF receptors in brain (Grigoriadis et al., Neuropsychopharmacology 2:53 (1989)).

There has also been a role postulated for CRF in the etiology of anxiety-related disorders. CRF produces anxiogenic effects in animals and interactions between benzodiazepine/non-benzodiazepine anxiolytics and CRF have been demonstrated in a variety of behavioral anxiety models (D. R. Britton et al., Life Sci. 31:363 (1982); C. W. Berridge and A. J. Dunn Regul. Peptides 16:83 (1986)). Preliminary studies using the putative CRF receptor antagonist α-helical ovine CRF (9-41) in a variety of behavioral paradigms demonstrate that the antagonist produces "anxiolytic-like" effects that are qualitatively similar to the benzodiazepines (C. W. Berridge and A. J. Dunn Horm. Behav. 21:393 (1987), Brain Research Reviews 15:71 (1990)). Neurochemical, endocrine and receptor binding studies have all demonstrated interactions between CRF and benzodiazepine anxiolytics providing further evidence for the involvement of CRF in these disorders. Chlordiazepoxide attenuates the "anxiogenic" effects of CRF in both the conflict test (K. T. Britton et al., Psychopharmacology 86:170 (1985); K. T. Britton et al., Psychopharmacology 94:306 (1988) and in the acoustic startle test (N. R. Swerdlow et al., Psychopharmacology 88:147 (1986)) in rats. The benzodiazepine receptor antagonist (Ro15-1788), which was without behavioral activity alone in the operant conflict test, reversed the effects of CRF in a dose-dependent manner while the benzodiazepine inverse agonist (FG7142) enhanced the actions of CRF (K. T. Britton et al., Psychopharmacology 94:306 (1988)).

The mechanisms and sites of action through which the standard anxiolytics and antidepressants produce their therapeutic effects remain to be elucidated. It has been hypothesized, however, that they are involved in the suppression of the CRF hypersecretion that is observed in these disorders. Of particular interest is that preliminary studies examining the effects of a CRF receptor antagonist (α-helical CRF₉₋₄₁) in a variety of behavioral paradigms have demonstrated that the CRF antagonist produces "anxiolytic-like" effects qualitatively similar to the benzodiazepines (for review, see G. F. Koob and K. T. Britton, In: Corticotropin-Releasing Factor: Basic and Clinical Studies of a Neuropeptide, E. B. De Souza and C. B. Nemeroff eds., CRC Press p. 221 (1990)).

In order to study these specific cell-surface receptor proteins, compounds must be identified that can interact with the CRF receptor in a specific manner dictated by the pharmacological profile of the characterized receptor. Toward that end, there is evidence that the direct CRF antagonist compounds and compositions of this invention, which can attenuate the physiological responses to stress-related disorders, will have potential therapeutic utility for the treatment of depression and anxiety-related disorders. All of the aforementioned references are hereby incorporated by reference.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the present invention it has been discovered that the provided compounds are useful as antagonists of Corticotropin Releasing Factor and for the treatment of affective disorders, anxiety, or depression.

The present invention also provides methods for the treatment of affective disorder, anxiety or depression by administering to a compromised host a therapeutically effective amount of a compound of formula (I) as described above. By therapeutically effective amount is meant an amount of a compound of the present invention effective to antagonize abnormal levels of CRF or treat the symptoms of affective disorder, anxiety or depression in a host.

The compounds herein described may have asymmetric centers. All chiral, diastereomeric, and racemic forms are included in the present invention. Many geometric isomers of olefins, C═N double bonds, and the like can also be present in the compounds described herein, and all such stable isomers are contemplated in the present invention. It will be appreciated that certain compounds of the present invention contain an asymmetrically substituted carbon atom, and may be isolated in optically active or racemic forms. It is well known in the art how to prepare optically active forms, such as by resolution of racemic forms or by synthesis, from optically active starting materials. Also, it is realized that cis and trans geometric isomers of the compounds of the present invention are described and may be isolated as a mixture of isomers or as separated isomeric forms. All chiral, diastereomeric, and racemic forms and all geometric isomeric forms of a structure are intended, unless the specific stereochemistry or isomer form is specifically indicated.

When any variable (for example, R¹ through R¹⁰, m, n, A, w, Z, etc.) occurs more than one time in any constituent or in formula (I) or any other formula herein, its definition on each occurrence is independent of its definition at every other occurrence. Thus, for example, in --NR⁸ R⁹, each of the substituents may be independently selected from the list of possible R⁸ and R⁹ groups defined. Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

SYNTHESIS

The novel substituted-2-pyridinamines, substituted triazines, substituted pyridines and substituted anilines of the present invention can be prepared by one of the general schemes outlined below (Scheme 1-23).

Compounds of the Formula (I), wherein Z is CR² and J is CX' and K and L are both CH, can be prepared as shown in Scheme 1. 2-Hydroxy-4,6-dialkylpyrimidine (II) was converted to the corresponding derivative (III) with an appropriate leaving group in the 2-position such as, but not limited to, Cl, Br, SO₂ CH₃, OSO₂ CH₃, or OSO₂ C₆ H₄ --CH₃, or SCH₃ by treatment with phosphorous oxychloride (POCl₃), phosphorous oxybromide (POBr₃), methanesulfonyl chloride (MsCl), p-toluenesulfonyl chloride (TsCl), or sodium thiomethoxide optionally followed by oxidation with hydrogen peroxide, chlorine gas, or an organic peracid, such as, m-chloroperbenzoic ##STR14## acid, respectively. This derivative was reacted with the appropriate 2,4-substituted aniline (IV) in a high boiling solvent, such as, but not limited to, ethylene glycol, methoxyethoxyethanol etc., or in an aprotic solvent such as tetrahydrofuran, dioxane, toluene, xylene, or N,N-dimethyformamide, facilitated by the optional use of a base such as sodium hydride (NaH), lithium diisopropylamide (LDA), which are preferred. The coupled product (V) was treated with a base such as NaH or LDA in an aprotic solvent such as tetrahydrofuran (THF) or N,N-dimethylformamide (DMF) or in a combination of potassium tert-butoxide in t-butanol (tBuOK/tBuOH) followed by an alkylating agent R⁴ L', such as an alkyl iodide, mesylate or tosylate to afford the corresponding alkylated product of Formula (I).

The compounds of Formula (I), wherein V and Y are N and Z, J, K, and L are all CH, can be prepared as shown in Scheme 2. The substituted aniline (VI) was converted to the corresponding guanidinium salt (VII) by treatment with the appropriate reagent such as cyanamide. ##STR15## The guanidinium salt (VII) was reacted with a β-diketone (VIII) in the presence of a base such as potassium carbonate (K₂ CO₃) in N,N-dimethylformamide (DMF) or in an alcoholic solvent in the presence of the corresponding alkoxide to afford the corresponding pyrimidine (IX). This was subsequently alkylated to provide (X), a compound of Formula (I) where X' is hydrogen, by conditions identical to those described in Scheme 1.

Compounds of the Formula (I), wherein V and Y are N and Z, J, K, and L are all CH and R³ is NR⁶ R⁷, can be prepared as shown in Scheme 3. Treatment of 2,4-dichloro-6-alkylpyrimidine (XI) with a primary or secondary amine in the presence of a non-nucleophilic base such as a trialkylamine afforded selectively the corresponding 4-substituted amino adduct (XII). ##STR16## This in turn, was reacted with the substituted aniline (IV) under conditions identical to those described in Scheme 1 to afford the corresponding secondary pyrimidinamine (XIII). This was alkylated under conditions described in Schemes 1 and 2. ##STR17##

Compounds of Formula (I) wherein J, K, and L are CH and Z is CR² and V and Y are N can also be prepared by the route outlined in Scheme 4. The guanidinium salt (XII) was reacted with a β-ketoester (XV) in the presence of a base such as an alkoxide in the corresponding alcoholic solvent to give the adduct (XVI). Treatment of the hydroxy group in (XVI) with either phosphorous oxychloride, phosphorous oxybromide, methanesulfonyl chloride, p-toluenesulfonyl chloride, or trifluoromethanesulfonic anhydride provided (XVII), wherein the L is a leaving group and is, respectively, Cl, Br, I, OMs, OTs, or OTf. The L group of (XVII) was displaced with a nucleophile such as NR⁶ R⁷, OR⁶, SR⁶, CN, an organolithium, organomagnesium, organosodium, organopotassium, an alkyl cuprate, or in general an organometallic reagent to the corresponding adduct (IX), which was further alkylated under the standard conditions to produce (XVIII).

Compounds of the Formula (I) that are substituted at the 2-position of the phenyl ring could be prepared as outlined in Scheme 5. ##STR18##

Compounds of the Formula (I) wherein X is other than bromine can be prepared by the intermediates shown in Scheme 5. Reaction of the 2-halo compound (V) wherein X is bromine or hydrogen with a metalating agent such as, but not limited to, n-BuLi or t-BuLi in an aprotic solvent, preferably ether or tetrahydrofuran, provided the corresponding 2-lithio intermediate (X=Li, not isolated) which was further reacted with an electrophile such as iodine or trimethyltin chloride ((CH₃)₃ SnCl) to give the corresponding 2-substituted product (XIX). These intermediates can also be further reacted using palladium-catalyzed coupling reactions well known to one of skill in the art to prepare the compounds of the invention.

Compounds of the Formula (I) wherein Z, K and L are all CH, J is N or CH, and R⁴ is ethyl can be prepared as illustrated in Scheme 6. Sequential addition/re-oxidation of an alkyllithium to 2-chloropyrimidine can provide intermediate (XXII) wherein the R¹ and R³ can be independent of one another. Displacement of the chlorine by a suitable nitrogen nucleophile such as an aniline under similar conditions of Scheme 1, followed by attachment of the R⁴ group by alkylation in an analogous method of Schemes 1 or 2 provide the compounds of the invention. ##STR19##

Compounds of the Formula (I) wherein Z is N can be prepared according to the method outlined in Scheme 7. Known triazine (XXIII), synthesis of which is reported in J. Amer. Chem. Soc. 77:2447 (1956), can be reacted with a substituted aniline (IV) in a analogous manner to Scheme 1. Similarly, the 2,4 dichloro 6-methyltriazine, which can be prepared via the method reported in U.S. Pat. No. 3,947,374can be coupled to the substituted aniline (IV) to provide (XXIV) where R³ is chlorine. Nucleophilic addition in protic or aprotic solvents allows for a variety of substituents at this position (XXV). Alkylation of the secondary amine as previously described provide triazine compounds of formula (I). ##STR20##

This undergoes base catalyzed cyclization to a 1-aryl-2-amino-4-cyanopyrrole LII. Reaction with an appropriate 1,3-dicarbonyl compound gives the desired 7-azaindole LIII. ##STR26##

The nitrile substituent at position 3 of structure LIII is readily removed by refluxing the 3-cyano compound with 65% sulfuric acid. Position 3 then can be resubstituted by halogenation or nitration. Reduction of the nitro group can provide the 3-amino substituent.

Alternatively, the nitrile group can be converted to desired L groups by methods described in "Comprehensive Organic Transformations", by Richard C. Larock, VCH Publishers, Inc., New York, N.Y., 1989. For instance, the nitrile group can be reduced with diisobutylaluminum hydride to give the 3-aldehyde. The 3-aldehyde can be reduced via the hydrazone under Wolff-Kishner conditions (KOH in hot diethylene glycol) to give L=methyl. Furthermore, the aldehyde can be converted to L═CH═CH₂ by adding it to a mixture of methyltriphenylphosphonium bromide and potassium tertiary-butoxide in tetrahydrofuran (Wittig reaction). Reduction of the ethenyl group to give L═CH₂ CH₃ can be effected by hydroboration-protonolysis (J. Am. Chem. Soc. 81:4108 (1959)).

Scheme 13 generally provides a mixture isomeric in substituents R¹ and R³, which then can be separated. Sometimes the preferred isomer is the one obtained in lower yield. In the event Scheme 14 can be used to prepare the preferred isomer. Intermediate LII is treated with the appropriate acyl- or aroyl-acetic ester under either thermal or acid-catalyzed conditions to give the 6-hydroxy compound LV. Compound LV is converted to the 6-chloro compound LVI and de-cyanylated to compound LVII. When R¹ substituents other than chloro are desired, the chloro group can be converted to other substituents. For instance, treatment of compound LVII with an alkyl Grignard reagent can provide compound LVIII where R¹ ═alkyl. Heating with a primary or secondary amine can provide compound LVIII where R¹ ═amino. ##STR27##

Scheme 15 affords another route to compounds of this invention. Intermediate LII can be treated with the appropriate acylacetaldehyde dialkyl acetal under acid catalyzed conditions to give compounds LXa and LXb, 7-azaindoles unsubstituted at positions 4 and 7 respectively. Compound LXa can be oxidized with m-chloroperoxybenzoic acid to give the N-oxide compound LXI. Heating compound LXI with phosphorus oxychloride can give compound XIIa, which can be decyanylated to compound LXIII.

Compound LXIV where R³ is an amino substituent can be prepared by heating LXIII with the appropriate amine; where R³ =alkoxide, the metal alkoxide can be heated with LXIII; where R³ =aryl, compound LXIII can treated with the arylboronic acid in the presence of tetrakis(triphenylphosphine)palladium (TTPP) and sodium carbonate; and where R³ =alkyl, alkenyl, aralkyl, and cycloalkyl, compound LXIII can be coupled with the appropriate organotin reagent, also in the presence of TTPP.

Compound LXIV where R³ is a nitro group can be prepared by nitration of LXI, decyanylation, and reduction of the N-oxide with a trivalent phosphorus compound such as triethyl phosphite.

Compound LXb can be substituted in the 6 position using methods described for the substitution of LXa. ##STR28##

The novel 7-azabenzimidazoles of this invention can be prepared as outlined in Scheme 16 where R²⁹ is nitrogen. Compounds L and LXV can react upon heating in the presence of a base, e.g. sodium hydride, to give the diarylamine LXVI. Reduction of the nitro group with stannous chloride can give LXVII, which can be closed to the 7-azabenzimidazole LXVIII. ##STR29##

The purines of this invention can be prepared as shown in Schemes 17 and 18.

Compounds L and LXIX (J. Heterocyclic Chem. 28:465 (1991)) can be heated in the presence of a base, e.g. sodium hydride, to give compound LXX. Heating LXX with the appropriate carboxylic acid in the presence of a mineral acid catalyst can give LXXI where R²⁸ is hydrogen, alkyl, alkenyl, or alkynyl. The chloro substituent can then be converted to R³ to give compounds LXXII by using one of the methods described above for the introduction of R³ to obtain compounds LXIV. ##STR30##

Scheme 18 can be used to prepare purines where R²⁸ is halogen or alkoxide. Compounds LXX can be heated with a dialkyl carbonate, such as diethyl carbonate, to give the carbonyl compound LXXIII; if the conversion is undesirably slow, more reactive species such as trichloromethyl chlorocarbonate or carbonyl diimidazole can be used in place of diethyl carbonate. The chloro substituent can then be converted to R³ to give LXXIV by using one of the methods described above for the introduction of R³ to obtain LXIV. Heating LXXIV with phosphorus oxychloride can give the 2-chloropurine, LXXV. To prepare the 2-alkoxypurines, LXXVI, LXXV can be heated with a metal salt of the alcohol R³¹ OH, e.g. the sodium or potassium salt, wherein in R³¹ is C₁ -C₄ alkyl. ##STR31##

The method of synthesis of the 7-azaindolines of this invention is shown in Scheme 19.

A number of compounds of the general structure LXXVIII with desired R¹ and R² groups have been described by W. Paudler and T.-K. Chem, J. Heterocyclic Chem. 7:767 (1970). These can be oxidized with a peracid, e.g. m-chloroperoxybenzoic acid, to the sulfone LXXIX. Sulfone LXXIX can be heated in the presence of the desired aniline and a base, e.g. sodium hydride to give the diaryl amine LXXX. Alkylation of LXXX with the desired unsubstituted or 4-substituted-3-butynyl iodide (or 3-butynol mesylate) can give LXXXI. LXXXI can undergo an intramolecular Diels-Alder reaction to give LXXXII.

In a number of cases, the desired 4-substituted 3-butynyl iodide is not readily available or is unstable. In that event unsubstituted 3-butynyl iodide is used to give compound LXXXII where R^(3=H). ##STR32##

The synthesis of the 5,7-diazaindoles of this invention is outlined in Scheme 20.

The desired formamidine LXXXIII can be treated with LXXXIV in the presence of sodium ethoxide in ethanol to give the pyrimidine LXXXV. Refluxing LXXXV in phosphorus oxychloride gives the dichloropyrimidine LXXXVI. Compound LXXXVI can be converted to the carbonyl compound LXXXVII by treatment with one equivalent of ozone at -78° to give an ozonide, which on treatment with sodium iodide and acetic acid gives the desired carbonyl compound. The preparation of LXXXVII (R¹ =H, R²⁸ =CH₃ and R¹ =R²⁸ =CH₃) by a different route has been described by E. Basagni, et. al., Bull. Soc. Chim. Fr., 4338 (1969).

Before the coupling reaction, the carbonyl of compound LXXXVII is protected by treatment with 2,2-dimethoxypropane in the presence of a catalytic amount of acid to give compound LXXXVIII. Compound LXXXVIII is then coupled with the appropriate aniline L by heating in the presence of a base, e.g. sodium hydride, to give compound LXXXIX. Compound LXXXIX can be cyclized to give the 5,7-diazaindole XC, the target compound wherein R³ =Cl. Compound XC is also a useful intermediate for the preparation of Compounds XCI with other R³ groups. For example, heating the chloro compound with the appropriate amine gives the desired amino compound. Heating with a metal alkoxide gives the desired alkoxy compound. Treating compound XC(R³ =Cl) with R³ MgBr (R³ =alkyl, aryl, or aralkyl) converts the chloro compound to the desired alkyl, aryl, or aralkyl compound XCI. ##STR33##

Compounds wherein R⁵ is dimethylhydroxymethyl, X' is iodine and R¹ and R³ are chlorine can be prepared according to scheme 21. Ethyl 4-aminobenzoate is iodinated in a methylene chloride/water (50:50) mixture in the presence of sodium bicarbonate to provide compound (XCII). This material is coupled to cyanuric chloride, then the secondary amine is alkylated in an analogous manner to that in Scheme 1 to yield XCIII. Compound XCIII is treated with 5 equivalents of MeMgBr to provide the desired material of formula (XCIV). ##STR34##

Scheme 22 depicts the synthesis of compounds of Formula (I), where Y=N, Z=CR² and R³ is COR²⁵, CH(OH)R²⁵ or C(OH)R²⁵ R^(25a). An ester of Formula (XCVI) may be converted to an amide of Formula (C) by treatment with an amine of Formula HN(OR^(a))R^(b), where R^(a) and R^(b) are lower alkyl (preferably Me), in the presence of a trialkylaluminum reagent (preferably Me₃ Al) in an inert solvent preferably an aromatic hydrocarbon (e.g., benzone) or an ethereal solvent (e.g., tetrahydrofuran) as taught by the prior art (cf. J. I. Levin, E. Turos, S. M. Weinreb, Synthetic Communications 12:989-993 (1982)). Amides of Formula (C) may be converted to ketones of Formula (CI) by treatment with an organolithium reagent R²⁵ Li or an organomagnesium halide R²⁵ MgX, where X=Cl, Br or I, in an inert solvent, preferably an ethereal solvent (e.g., diethyl ether or tetrahydrofuran), as taught by the prior art (cf. S. Nahm and S. M. Weinreb, Tetrahedron Letters 22:3815-3818 (1981)). Alternatively, ketones of Formula (CI) can be prepared from acids of Formula (XCV) by treatment with an organolithium reagent R²⁵ Li in the presence of an inorganic salt (preferably a transition metal halide (e.g., CeCl₃)) in an inert solvent (preferably an ethereal solvent (e.g., tetrahydrofuran)) as taught by the prior art (cf. Y. Ahn and T. Cohen, Tetrahedron Letters 35:203-206 (1994)). Alternatively, esters of Formula (XCVI) can be converted directly to ketones of Formula (XCVIII) by reaction with an organolithium reagent R²⁵ Li or an organomagnesium halide R²⁵ MgX, where X=Cl, Br or I, in an inert solvent (preferably an ethereal solvent e.g., diethyl ether or tetrahydrofuran) at temperatures ranging from -100 to 150° C. (preferably -78 to 80° C.) (cf. J. March, Advanced Organic Chemistry (New York: J. Wiley and Sons, 1985, pp. 433-434). Ketones of Formula (XCVIII) can be converted to alcohols of Formula (XCIX) by reaction with an organolithium reagent R^(25a) Li or an organomagnesium halide R^(25a) MgX, where X=Cl, Br or I, in an inert solvent (preferably an ethereal solvent (e.g. diethyl ether or tetrahydrofuran) at temperatures ranging from -100 to 150° C. (preferably -78 to 80° C.) (cf. The above March reference, pp. 434-435). Alternatively, esters of Formula (XCVI) can be converted to alcohols of Formula (XCIX) by reaction with an organolithium reagent R^(25a) Li or an organomagnesium halide R^(25a) MgX, where X=Cl, Br or I, in an inert solvent (preferably an ethereal solvent e.g., diethyl ether or tetrahydrofuran) at temperatures ranging from -100 to 150° C. (preferably -78 to 100° C.), preferably using an excess amount of organometallic reagent (cf. the above March reference, pp. 434-435). In this last instance, R²⁵ =R^(25a). Ketones of Formula (XCVIII) can be converted to alcohols of Formula (C) by treatment with a reducing agent in an inert solvent. Such reducing agents include, but are not limited to, alkali metal aluminum hydrides, preferably lithium aluminum hydride, alkali metal borohydrides (preferably sodium borohydride), alkali metal trialkoxyaluminum hydrides (such as lithium tri-t-butoxyaluminum hydride), dialkylaluminum hydrides (such as di-isobutylaluminum hydride), borane, dialkylboranes (such as di-isoamyl borane), alkali metal trialkylboron hydrides (such as lithium triethylboron hydride). Inert solvents include lower alkyl alcohols of 1 to 6 carbons, ethereal solvents (such as diethyl ether or tetrahydrofuran), aromatic or non-aromatic hydrocarbons of 6 to 10 carbons. Reaction temperatures for the reduction range from about -78° to about 200° C., preferably about 0° to about 120° C. The choice of reducing agent and solvent is known to those skilled in the art as taught in the above cited March reference (Advanced Organic Chemistry, pp. 1093-1110). ##STR35##

Compounds of Formula (I) can also be prepared by the procedures outlined in Scheme 23. A compound of Formula (CI) (Formula I, where Z=CR², Y=N, R³ =(CHR¹¹)_(p) CN) can be reacted with sodium azide and ammonium chloride in a polar solvent at high temperatures (preferably 70 to 150° C.) to give a tetrazole of Formula (CII) as taught by the prior art (cf. R. N. Butlet, Tetrazoles, in Comprehensive Heterocyclic Chemistry; A. R. Katritzky, C. W. Rees, Eds.; (New York: Pergamon Press, 1984), pp. 828-832). Such polar solvents may be dialkylformamides (preferably N,N-dimethylformamide), dialkylacetamides, (preferably N,N-dimethylacetamide), cyclic amides, (preferably N-methylpyrrolidinone), dialkyl sulfoxides (preferably dimethyl sulfoxide) or dioxane. A compound of Formula (CIII) (Formula I, where Y=N, Z=CR² and R³ =COCH₃) may be treated with a halogenating agent in an inert solvent to give a haloketone of Formula (CIV). Such halogenating agents include bromine, chlorine, iodine, N-halosuccinimides (e.g. N-bromosuccinimide), N-halophthalimides (e.g., N-bromophthalimide) or N-tetrasubstituted ammonium perbromides (e.g., tetraethylammonium perbromide) (cf. The above March reference, Advanced Organic Chemistry, pp. 539-531; S. Kajiigaeshi, T. Kakinami, T. Okamoto, S. Fujiisaki, Bull. Chem. Soc. Japan 60:1159-1160 (1987) and references cited therein). Inert solvents include lower halocarbons of 1 to 6 carbons and 2 to 6 halogens (preferably dichloromethane or dichloroethane), dialkyl ethers of 4 to 10 carbons, cyclic ethers of 4 to 10 carbons (preferably dioxane) or aromatic hydrocarbons to 6 to 10 carbons. Haloketones of Formula (CIV) may be converted to imidazoles of Formula (CVII) by treatment with formamide with or without an inert solvent as taught by the prior art (H. Brederick and G. Theilig, Chem. Ber. 86:88-108 (1953)). Alternatively, ketones of Formula (CIII) may be converted to vinylogous amides (CV) by reaction with N,N-di(lower alkyl)formamide di(lower alkyl)acetals (e.g., N,N-dimethylformamide dimethyl acetal) or Gold's reagent ((dimethylaminomethyleneaminomethylene)-dimethylammonium chloride) in an inert solvent with or without base as taught by the prior art (cf. J. T. Gupton, S. S. Andrew, C. Colon, Synthetic Communications 12:35-41 (1982); R. F. Abdulla, K. H. Fuhr, J. Organic Chem. 43:4248-4250 (1978)). Such inert solvents include aromatic hydrocarbons of 6 to 10 carbons, lower alkyl alcohols of 1 to 6 carbons, dialkyl ethers of 4 to 10 carbons, or cyclic ethers of 4 to 10 carbons (preferably dioxane). Such bases may include a tertiary amine, an alkali metal hydride (preferably sodium hydride), an aromatic amine (preferably pyridine), or an alkali metal carbonate or alkoxide. Vinylogous amides (CV) can be condensed with hydrazine in an inert solvent to form pyrazoles of Formula (CVI) as taught by the prior art (cf. G. Sarodnick, Chemische Zeitung 115:217-218 (1991); Y. Lin, S. A. Lang, J. Heterocyclic Chem. 14:345 (1977); E. Stark et al., Chemische Zeitung 101:161 (1977); J. V. Greenhill, Chem. Soc. Reviews 6:277 (1977)). Such inert solvents include aromatic hydrocarbons of 6 to 10 carbons, lower alkyl alcohols of 1 to 6 carbons, dialkyl ethers of 4 to 10 carbons, or cyclic ethers of 4 to 10 carbons (preferably dioxane). ##STR36##

The purines and 8-aza-purines of the present invention are readily synthesized following the methods shown in Schemes 24 and 25. The purine (CXI) is derived from an appropriately substituted pyrimidine (CVIII). The trisubstituted hydroxypyrimidine is nitrated under standard conditions with fuming nitric acid. Following conversion of the hydroxy compound to the chloro derivative via treatment with phosphorus oxychloride, reduction of the nitro group with iron powder in acetic acid and methanol yielded the aminopyrimidine (CIX). Compound CIX is reacted with the appropriately substituted aniline in the presence of base catalyst to yield an anilinopyrimidine (CX), which was then converted to the desired purine (CXI) via reaction with triethylorthoformate in acetic anhydride. Starting from compound CX, the desired 8-aza-purine can be prepared via reaction with sodium nitrite in acetic acid. ##STR37##

If R³ of the purine is a chloro group, that substituent can be further elaborated to other R³ substituents as shown in Scheme 25. Compound (CXII), wherein R³ is chlorine, is reacted with a nucleophile with or without an inert solvent at temperatures ranging from 20° C. to 200° C., to effect the formation of the 8-azapurine (CXIII). In a similar fashion, the R³ of an appropriately substituted purine (CXI) may be converted to other functional groups to yield the purine (CXIV) having the desired substitution pattern. Similarly, if R¹ is a chloro group, it may be converted to another functional group via reaction with an appropriate nucleophile. Nucleophiles include amine, hydroxy, or mercapto compounds or their salts. ##STR38##

Compounds of the Formula (I) wherein J, K, and/or L are N, such as (CXXVII), (CXXVIII), (CXXIX), or (CXXX), were prepared according to Schemes 26 and 27. The preparation of the lower ring heterocycle of the compound of the Formula (I) is shown in Scheme 26. 2,4-Dihydroxy-5-nitropyrimidine (CXV) was first converted to the dichloro compound (CXVI) via treatment with phosphorus oxychloride. Compound (CXVI) was then converted to the symmetrically bis-substituted pyrimidines, (CXVII) and (CXVIII), via reaction with the appropriate R⁵ or X group radicals, MR⁵ and MX, respectively, where M is a metal atom. It is understood that compounds of the Formula (I) wherein R⁵ and X have the same definition fall within the scope of this invention. A method of forming the unsymmetrically bis-substituted compounds (CXIX) and (CXX) is treatment of (CXVI) with equimolar amounts of MR⁵ and X to form a statistical distribution of products, (CXVII), (CXVIII), (CXIX) and (CXX), which can be purified by standard techniques, such as, recrystallization or chromatography.

The desired (N-pyrimidino-N-alkyl)aminopyrimidines of the present invention were prepared according to Scheme 27. An appropriately substituted 2-hydroxypyrimidine (CXXI) was converted to the 2-chlorpyrimidine (CXXII) via treatment with phosphorus oxychloride. The intermediate (N-pyrimidino)aminopyrimidines, (CXXIII), (CXXIV), (CXXV), and (CXXVI), were prepared via treatment of (CXXII) with the appropriate 5-aminopyrimidine, (CXVII), (CXVIII), (CXIX) and (CXX) respectively, in the presence of a base, such as, NaH. Simple alkylation of the amino groups in (CXXIII), (CXXIV), (CXXV), and (CXXVI) via treatment with R⁴ I and sodium hydride gave the desire (N-pyrimidino-N-alkyl)aminopyrimidines, (CXXVII), (CXXVIII), (CXXIX), and (CXXX). ##STR39##

The (N-heterocycle-N-alkyl)aminopyrimidines or N-heterocycle-N-alkyl)aminotriazines of the present invention may also be prepared according to Scheme 28. Commercially available amino substituted heterocycles (CXXXI) may be brominated using a tetrasubstituted ammonium tribromide, preferably benzyltrimethylammonium tribromide (BTMA Br₃) to yield the appropriately substituted o-bromo-aminoheterocycle (CXXXII). Such reactions are carried out in an inert solvent, such as, lower alcohols or halocarbons of 1 to 4 carbons and 1 to 4 halogens in the presence of a base, such as, alkali metal or alkaline earth metal carbonates. Compound (CXXXII) is then coupled to a substituted pyrimidine or triazine (CXXXIII) to form an (N-heterocycle-N-alkyl)aminopyrimidine (CXXXIVa) or (N-heterocycle)aminotriazine (CXXXIVb). (CXXXIVa or b) is then further alkylated in the presence of a base to the target (N-heterocycle-N-alkyl)aminopyrimidine (CXXXVa) or (N-heterocycle-N-alkyl)aminotriazine (CXXXVb), respectively. ##STR40##

Description of Scheme 29

Alternatively purines (CXIV) and triazolopyrimides (CXIII) of the present invention may be readily synthesized by following one of the approaches outlined in Scheme 29. Substituted anilines may be readily coupled with 2,4-dichloro-5-nitropyrimidines (CXXXVI) in the presence or absence of solvents such as DMSO or DMF or THF to provide compounds CXXXVII or CXXXVIII. CXXXVII or CXXXVIII are readily elaborated to compounds CX or CSII by following standard conditions outlined in Schemes 24, 25 and 29. In another approach nucleophiles R³ H may be added to CXXXVI in the presence or absence of bases in solvents such as halogenated solvents, alkyl ethers and cyclic ethers to afford compound CXXXIX. Substituted anilines may be readily added to CXXXIX in the presence or absence of solvents such as dialkylsulfoxide or N,N-dialkylformamides or N,N-dialkylacetamides or cyclic amides such as N-methylpyrrolidinone to provide compounds of structure CXL. Starting from compound CXL, compounds of the present invention purines (CXIV) or triazolopyrimidines (CXIII) can be prepared under standard conditions described in Schemes 24 and 29.

An alternative synthesis of triazolopyridines is described in Scheme 30: ##STR41##

Treatment of compounds of Formula (CLIV) with an aliphatic or aromatic amine in an appropriate organic solvent but not limited to, alkyl alcohols such as methanol, ethanol, propanol, butanol, alkyl alkanoates such as ethyl acetate, alkanenitriles such as acetonitrile, dialkyl formamides such as DMF gives the corresponding ammonium salt, which upon treatment with POCl₃ at temperatures from 25 to 120° C., give compounds of Formula (CLVI). Treatment of compounds of Formula (CLVI) with appropriate primary amines in an organic solvent such as but not limited to alkyl alcohols such as methanol, ethanol, propanol, butanol, alkyl alkanoates such as ethyl acetate, alkanenitriles such as acetonitrile, dialkyl formamides such as DMF, dialkylsulfoxides at temperatures from 25 to 120° C. gives (CLVII). This is converted to (LXV) by treatment with POCl₃ at temperatures from 25 to 120° C. Compounds of Formula (LXV) can be coupled with Ar--NH₂ with or without the presence of solvent at temperatures from 25 to 200° C. to give products (LXVI). These can be converted to intermediates (LXVII) by reduction of the nitro group under a variety of reducing conditions, such as those used for the same conversion in Scheme 16 or other reducing reagents such as sodium dithionate, H2/catalyst, Fe/acid. The final cyclizaton can be carried out by treatment with NaNO2 in the presence of an acid such as acetic, hydrochloric to give triazolopyridines of Formula (LXVIII, R³ ═NHR⁶).

Treatment of compounds of Formula (CLIV) with POCl₃ in the presence of N,N-diethylaniline gives the dichloro compounds of Formula (CLV). These react selectively with secondary amines HNR⁵ R⁶ to give the 4-adduct of Formula (LXV). Compounds of Formula (LXV) can be subjected to the same reaction sequence described above to give compounds of Formula (LXVIII, R³ ═NR⁶ R⁷).

The compounds of the invention and their syntheses are further illustrated by the following examples and preparations. All temperatures are in degrees Celsius.

The mixture was stirred at 25° C. for 90 hours and partitioned between ethyl acetate (100 mL) and water (30 mL). The water was extracted with additional ethyl acetate (60 mL) and the combined organic extracts were washed with brine, dried, and concentrated in vacuo. The residue was chromatographed on silica gel using 8% ethyl acetate in hexanes to give the title compound (1.4 g) as the free-base.

The free-base was dissolved in ether (10 mL) and treated with a solution of anhydrous hydrogen chloride in ether (1 M, 6 mL). The precipitated solid was collected and dried under vacuum (mp 163-164° C.).

Part A: A mixture of 2,4-dichloro-6-methylpyrimidine (4 g, 24.54 mmoles), morpholine (2.14 mL, 24.54 mmoles) and N,N-diisopropylethylamine (4.52 mL) in ethanol (60 mL) was stirred at 0° C. for 3 hours, 25° C. for 24 hours, followed by reflux for 1 hour. The solvent was removed under vacuum and the residue was partitioned between ethyl acetate (200 mL) and aq. sodium hydroxide (1 M, 50 mL).

Utility

In vitro Receptor Binding Assay:

Tissue Preparation:

Male Sprague Dawley rats (180-200 g) were sacrificed by decapitation and the cortex was dissected on ice, frozen whole in liquid nitrogen and stored at -70° C. until use. On the day of assay, frozen tissue was weighed and homogenized in 20 volumes of ice cold buffer containing 50 mM Tris, 10 mM MgCl₂, 2 mM EGTA, pH 7.0 at 22° C. using a Polytron (Brinkmann Instruments, Westbury, N.Y.; setting 6) for 20 s. The homogenate was centrifuged at 48,000×g for 10 min at 4° C. The supernatant was discarded, and the pellet was re-homogenized in the same volume of buffer and centrifuged at 48,000×g for 10 min at 4° C. The resulting pellet was resuspended in the above buffer to a final concentration of 20-40 mg original wet weight/mL and used in the assays described below. Protein determinations were performed according to the method of Lowry (Lowry et al., J. Biol. Chem. 193:265 (1951)) using bovine serum albumin as a standard.

CRF Receptor Binding:

Receptor binding assays were carried out essentially as described by E. B. De Souza, J. Neurosci. 7:88 (1987).

Saturation Curve Analysis

In saturation studies, 100 μl ¹²⁵ I-ovine CRF (50 pM-10 nM final concentration), 100 μl of assay buffer (with or without 1 mM r/hCRF final concentration, to define the non-specific binding) and 100 μl of membrane suspension (as described above) were added in sequence to 1.5 mL polypropylene microfuge tubes for a final volume of 300 μl. All assays were carried out at equilibrium for 2 h at 22° C. as described by E. B. De Souza, J. Neurosci. 7:88 (1987). The reaction was terminated by centrifugation of the tubes in a Beckman microfuge for 5 min at 12,000×g. Aliquots of the supernatant were collected to determine the "free" radioligand concentation. The remaining supernatant was aspirated and the pellets washed gently with ice-cold PBS plus 0.01% Triton X-100, centrifuged again and monitored for bound radioactivity as described above. Data from saturation curves were analyzed using the non-linear least-squares curve-fitting program LIGAND (P. J. Munson and D. Rodbard, Anal. Biochem. 107:220 (1980)). This program has the distinct advantage of fitting the raw experimental data on an untransformed coordinate system where errors are most likely to be normally distributed and uncorrelated with the independent variable. LIGAND does not expect the non-specific binding to be defined arbitrarily by the investigator, rather it estimates the value as an independent variable from the entire data set. The parameters for the affinity constants (K_(D)) and receptor densities (B_(max)) are also provided along with statistics on the general "fit" of the estimated parameters to the raw data. This program also offers the versatility of analyzing multiple curves simultaneously, thus improving the reliability of the data analysis and hence the validity of the final estimated parameters for any saturation experiment.

Competition Curve Analysis

In competition studies, 100 μl [¹²⁵ I] ovine CRF ([¹²⁵ I] oCRF; final concentration 200-300 pM) was incubated along with 100 μl buffer (in the presence of varying concentrations of competing ligands, typically 1 pM to 10 mM) and 100 μl of membrane suspensions as prepared above to give a total reaction volume of 300 μl. The reaction was initiated by the addition of membrane homogenates, allowed to proceed to equilibrium for 2 h at 22° C. and was terminated by centrifugation (12,000×g) in a Beckman microfuge to separate the bound radioligand from free radioligand. The resulting pellets were surface washed twice by centrifugation with 1 mL of ice-cold phosphate buffered saline and 0.01% Triton X-100, the supernatants discarded and the pellets monitored for radioactivity at approximately 80% efficiency. The level of non-specific binding was defined in the presence of 1 mM unlabeled rat/humanCRF(r/hCRF). Data from competition curves were analyzed by the program LIGAND. For each competition curve, estimates of the affinity of the radiolabeled ligand for the CRF receptor ([¹²⁵ I]CRF) were obtained in independent saturation experiments and these estimates were constrained during the analysis of the apparent inhibitory constants (K_(i)) for the peptides tested. Routinely, the data were analyzed using a one- and two-site model comparing the "goodness of fit" between the models in order to accurately determine the K_(i). Satistical analyses provided by LIGAND allowed the determination of whether a single-site or multiple-site model should be used. For both peptides (α-helical CRF₉₋₄₁ and d-PheCRF₁₂₋₄₁), as well as for all compounds of this invention, data were fit significantly to a single site model; a two-site model was either not possible or did not significantly improve the fit of the estimated parameters to the data.

The results of the in vitro testing of the compounds of the invention are shown in Table 17. It was found, for a representative number of compounds of the invention, that either form of the compound, be it the free-base or the hydrochloride salt, produced essentially the same inhibition value in the binding assay.

A compound is considered to be active if it has an K_(i) value of less than about 10000 nM for the inhibition of CRF. In Table 17, the K₁ values were determined using the assay conditions described above. The K_(i) values are indicated as follows: +++=<500 nM; ++=501-2000 nM; +=2001-10000 nM.

Inhibition of CRF-Stimulated Adenylate Cyclase Activity

Inhibition of CRF-stimulated adenylate cyclase activity was performed as described by G. Battaglia et al., Synapse 1:572 (1987). Briefly, assays were carried out at 37° C. for 10 min in 200 mL of buffer containing 100 mM Tris-HCl (pH 7.4 at 37° C.), 10 mM MgCl₂, 0.4 mM EGTA, 0.1% BSA, 1 mM isobutylmethylxanthine (IBMX), 250 units/mL phosphocreatine kinase, 5 mM creatine phosphate, 100 mM guanosine 5'-triphosphate, 100 nM oCRF, antagonist peptides (concentration range 10⁻⁹ to 10^(-6m)) and 0.8 mg original wet weight tissue (approximately 40-60 mg protein). Reactions were initiated by the addition of 1 mM ATP/³² P]ATP (approximately 2-4 mCi/tube) and terminated by the addition of 100 mL of 50 mM Tris-HCl, 45 mM ATP and 2% sodium dodecyl sulfate. In order to monitor the recovery of cAMP, 1 μl of [³ H]cAMP (approximately 40,000 dpm) was added to each tube prior to separation. The separation of [³² P]cAMP from [³² P]ATP was performed by sequential elution over Dowex and alumina columns. Recovery was consistently greater than 80%.

Representative compounds of this invention were found to be active in this assay. IC₅₀ ≦10,000 nanomolar.

In Vivo Biological Assay

The in vivo activity of the compounds of the present invention can be assessed using any one of the biological assays available and accepted within the art. Illustrative of these tests include the Acoustic Startle Assay, the Stair Climbing Test, and the Chronic Adminisitration Assay. These and other models useful for the testing of compounds of the present invention have been outlined in C. W. Berridge and A. J. Dunn Brain Research Reviews 15:71 (1990).

Compounds may be tested in any species of rodent or small mammal. Disclosure of the assays herein is not intended to limit the enablement of the invention.

The foregoing tests results demonstrate that compounds of this invention have utility in the treatment of imbalances associated with abnormal levels of corticotropin releasing factor in patients suffering from depression, affective disorders, and/or anxiety. The foregoing tests also demonstrate that compounds of this invention have utility in the treatment of uterine contraction disorders.

Compounds of this invention can be administered to treat said abnormalities by means that produce contact of the active agent with the agent's site of action in the body of a mammal. The compounds can be administered by any conventional means available for use in conjunction with pharmaceuticals either as individual therapeutic agents or in a combination of therapeutic agents. They can be administered alone, but are generally administered with a pharmaceutical carrier selected on the basis of the chosen route of administration and standard pharmaceutical practice.

The dosage administered will vary depending on the use and known factors such as the pharmacodynamic character of the particular agent, and its mode and route of administration; the recipient's age, weight, and health; nature and extent of symptoms; kind of concurrent treatment; frequency of treatment; and desired effect. For use in the treatment of said diseases or conditions, the compounds of this invention can be orally administered daily at a dosage of the active ingredient of 0.002 to 200 mg/kg of body weight. Ordinarily, a dose of 0.01 to 10 mg/kg in divided doses one to four times a day, or in sustained release formulation is effective in obtaining the desired pharmacological effect.

Dosage forms (compositions) suitable for administration contain from about 1 mg to about 100 mg of active ingredient per unit. In these pharmaceutical compositions, the active ingredient will ordinarily be present in an amount of about 0.5 to 95% by weight based on the total weight of the composition.

The active ingredient can be administered orally in solid dosage forms, such as capsules, tablets and powders; or in liquid forms such as elixirs, syrups, and/or suspensions. The compounds of this invention can also be administered parenterally in sterile liquid dose formulations.

Gelatin capsules can be used to contain the active ingredient and a suitable carrier, such as, but not limited to, lactose, starch, magnesium stearate, steric acid, or cellulose derivatives. Similar diluents can be used to make compressed tablets. Both tablets and capsules can be manufactured as sustained release products to provide for continuous release of medication over a period of time. Compressed tablets can be sugar-coated or film-coated to mask any unpleasant taste, or used to protect the active ingredients from the atmosphere, or to allow selective disintegration of the tablet in the gastrointestinal tract.

Liquid dose forms for oral administration can contain coloring or flavoring agents to increase patient acceptance.

In general, water, pharmaceutically acceptable oils, saline, aqueous dextrose (glucose), and related sugar solutions and glycols, such as propylene glycol or polyethylene glycol, are suitable carriers for parenteral solutions. Solutions for parenteral administration preferably contain a water soluble salt of the active ingredient, suitable stabilizing agents, and if necessary, buffer substances. Antioxidizing agents, such as sodium bisulfate, sodium sulfite, or ascorbic acid, either alone or in combination, are suitable stabilizing agents. Also used are citric acid and its salts, and EDTA. In addition, parenteral solutions can contain preservatives such as benzalkonium chloride, methyl- or propyl-paraben, and chlorobutanol.

Suitable pharmaceutical carriers are described in "Remington's Pharmaceutical Sciences", A. Osol, a standard reference in the field.

Useful pharmaceutical dosage-forms for administration of the compounds of this invention can be illustrated as follows:

Capsules

A large number of units in the form of capsules are prepared by filling standard two-piece hard gelatin capsules each with 100 mg of powdered active ingredient, 150 mg lactose, 50 mg cellulose, and 6 mg magnesium stearate.

Soft Gelatin Capsules

A mixture of active ingredient in a digestible oil such as soybean, cottonseed oil, or olive oil is prepared and injected by means of a positive displacement into gelatin to form soft gelatin capsules containing 100 mg of the active ingredient. The capsules are washed and dried.

Tablets

A large number of tablets are prepared by conventional procedures so that the dosage unit is 100 mg active ingredient, 0.2 mg of colloidal silicon dioxide, 5 mg of magnesium stearate, 275 mg of microcrystalline cellulose, 11 mg of starch, and 98.8 mg lactose. Appropriate coatings may be applied to increase palatability or delayed adsorption.

The compounds of this invention may also be used as reagents or standards in the biochemical study of neurological function, dysfunction, and disease.
